Product Traceability
The Merriam-Webster Online Dictionary defines traceability as “a: to follow the footprints, track, or trail of b: to follow or study out in detail or step by step… c: to discover by going backward over the evidence step by step … d: to discover signs, evidence, or remains of”. At EBAA Iron traceability allows you as the end user or us as the manufacturer to go backward into the production process and discover the signs that reveal the casting properties to the base level.

A Pandemic Of Another Kind: Addressing The Issues Of Clean Water Scarcity
As the coronavirus pandemic in some form continues to move across the world, health professionals are continually reminding us to exercise good hygiene and keep our hands clean. Easy enough, if you have access to a clean source of water. However, according to the USA Water Alliance, there are more than three million people presently that are without a dependable source of safe drinking water in the US. Around the world, this is also a bigger issue, as many people lack access to a source of safe drinking water to maintain their hygiene. Ongoing developments to ensure global water security, as well as provisions for wastewater sanitation services to avoid polluting water sources have been slowly adopted. Droughts and water scarcity have become issues that we are dealing with in the US and around the world.

Filter Membrane Predictive Maintenance
At manufacturing operations using ultrafiltration systems, the ultrafiltration membranes are used for numerous batches without replacement, using Clean-In-Place (CIP) operations in between batches to maintain filter performance. However, ineffective CIP cycles or long-term fouling or degradation of the filter membrane can result in increased cycle times to move the desired amount of product through the filter, lost yield as the product is unable to permeate the filter, or poor product quality as membrane failure may occur.

Fountain Testing Solutions10/29/2021
Accurate fountain (dampening) solution concentration control is essential for consistent, high-quality results in lithography. Low concentration can cause drying on the non-image area of the plate resulting in tinting, scumming, blanket piling, etc. High concentrations, on the other hand, bring about over-emulsification of the ink. This results in weakening of color strength and changes in ink rheology (body and flow properties). Correct concentration will allow the non-image areas of the plate to be appropriately wetted.

In the most recent edition of Water Innovations, there is not a single article focused on PFAS. That wouldn't be exceptional if not for the fact that discussion around per- and polyfluoroalkyl substances has so thoroughly dominated the water space lately. And yet, I penned this as an intro to the edition — just "a tiny bit of PFAS" content — because a small portion of PFAS is of the utmost importance in terms of treatment, policy, and cost.

ABOUT DRINKING WATER
In most developed countries, drinking water is regulated to ensure that it meets drinking water quality standards. In the U.S., the Environmental Protection Agency (EPA) administers these standards under the Safe Drinking Water Act (SDWA).
Drinking water considerations can be divided into three core areas of concern:
- Source water for a community’s drinking water supply
- Drinking water treatment of source water
- Distribution of treated drinking water to consumers
Drinking Water Sources
Source water access is imperative to human survival. Sources may include groundwater from aquifers, surface water from rivers and streams and seawater through a desalination process. Direct or indirect water reuse is also growing in popularity in communities with limited access to sources of traditional surface or groundwater.
Source water scarcity is a growing concern as populations grow and move to warmer, less aqueous climates; climatic changes take place and industrial and agricultural processes compete with the public’s need for water. The scarcity of water supply and water conservation are major focuses of the American Water Works Association.
Drinking Water Treatment
Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.
There are a variety of technologies and processes that can be used for contaminant removal and the removal of pathogens to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.
The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.
The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.
During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.
Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.
Drinking Water Distribution
Drinking water distribution involves the management of flow of the treated water to the consumer. By some estimates, up to 30% of treated water fails to reach the consumer. This water, often called non-revenue water, escapes from the distribution system through leaks in pipelines and joints, and in extreme cases through water main breaks.
A public water authority manages drinking water distribution through a network of pipes, pumps and valves and monitors that flow using flow, level and pressure measurement sensors and equipment.
Water meters and metering systems such as automatic meter reading (AMR) and advanced metering infrastructure (AMI) allows a water utility to assess a consumer’s water use and charge them for the correct amount of water they have consumed.
